iPrivacy: a Distributed Approach to Privacy on the Cloud
Ernesto Damiani, Francesco Pagano, Davide Pagano

TL;DR
This paper introduces iPrivacy, a distributed cloud storage system that enhances data privacy by combining client and cloud storage with fine-grained encryption and permission controls.
Contribution
It proposes a novel distributed architecture for cloud privacy, integrating client-side and server-side storage with secure data sharing mechanisms.
Findings
Implemented a system with in-memory RDBMS and row-level encryption.
Demonstrated secure data sharing with grant-and-revoke permissions.
Showed improved privacy control in distributed cloud storage.
Abstract
The increasing adoption of Cloud storage poses a number of privacy issues. Users wish to preserve full control over their sensitive data and cannot accept that it to be accessible by the remote storage provider. Previous research was made on techniques to protect data stored on untrusted servers; however we argue that the cloud architecture presents a number of open issues. To handle them, we present an approach where confidential data is stored in a highly distributed database, partly located on the cloud and partly on the clients. Data is shared in a secure manner using a simple grant-and-revoke permission of shared data and we have developed a system test implementation, using an in-memory RDBMS with row-level data encryption for fine-grained data access control
